Prevalence of Chronic Obstructive Pulmonary Disease in Kocaeli: An Industrialised City in Turkey

Abstract

Background: Chronic obstructive pulmonary disease (COPD) is an important cause of mortality worldwide. Aims: The aim of this study was to establish the prevalence of chronic obstructive pulmonary disease (COPD) in residents who were ≥40 years old and living in a heavily industrialised city of Turkey, Kocaeli, using the Burden of Obstructive Lung Disease Initiative questionnaire. Study Design: Cross-sectional study. Methods: 1035 residents ≥40 years old and living in Kocaeli were surveyed. Spirometry and the basic BOLD questionnaire was performed. Results: 946 subjects entered into the analysis. The prevalence of stage I or higher COPD was 13.3% (8.7% for women and 16.5% for men), the prevalence of COPD at GOLD stage II or higher was 7.1% (4.1% for women and 9.2% for men). We also noted a high prevalence of COPD in never-smokers. Conclusion: Besides cigarette smoking, occupational exposure to fumes, chemicals and dusts might have also contributed to the high prevalence of COPD noted in residents who were ≥40 years old and living in Kocaeli, Turkey. Turkish Başlık:Kocaeli'de Kronik Obstrüktif Akciğer Hastalığı Prevalansı: Türkiye'de Bir Sanayi Şehri Anahtar Kelimeler:KOAH, prevalans, anket, sigara içimi, yaş, epidemiyoloji Arkaplan: Kronik obstüktif akciğer hasalığı (KOAH) dünyada önemli bir mortalite nedenidir. Amaç: Çalışmanın amacı Türkiye' de bir sanayi şehri Kocaeli' de ≥40 yaş nüfusta kronik obstrüktif akciğer hastalığı (KOAH) prevalansını Burden of Obstructive Lung Disease Initiative anketini kullanarak tespit etmektir. Çalışma Tasarımı: Kesitsel çalışma Yöntemler: Kocaeli'de ikamet eden ≥40 yaş 1035 kişi çalışmaya alındı . Spirometre ve temel BOLD anketi uygulandı. Bulgular: Dokuz yüz kırk altı kişi analize alındı. GOLD Evre I ve üzeri KOAH prevalansı % 13.3 (kadınlarda %8.7 ve erkeklerde %16.5), GOLD Evre II ve üzeri KOAH prevalansı %7.1 (kadınlarda %4.1 ve erkeklerde % 9.2) tespit edildi. Hiç sigara içmeyenlerde de yüksek KOAH prevalansı tespit ettik. Sonuç: Türkiye Kocaeli'de ikamet eden ≥40 yaş kişilerde tespit edilen yüksek KOAH prevalansına sigara içimi dışında işyerlerinde kimyasal maddelere, dumana ve toza maruziyet de katkıda bulunuyor olabilir.
